The new session of the Folketing (Danish Parliament) commences the first Tuesday of October each year with Queen Margrethe and members of the Danish royal family attending the first sitting of the house. With the 2020 opening session just two weeks away, it’s great time to look back at all the hats Crown Princess Mary has worn to this event:

Chocolate felt pillbox with knotted bow in 2004; Tan felt gentle sidesweep in 2006 repeated in 2007 with lilac flower

Burgundy felt Philip Treacy cloche in 2008; Grey felt upturned brimmed hat by Suzanne Juul in 2009; Black hat with straw brim, felt crown and feather trim by Suzanne Juul in 2010

Natural straw calot with bow and flowers by Suszanne Juul in 2011; repeat of the black Suzanne Juul in 2012 and in 2013

A royal purple felt pillbox with feather trim by Jane Taylor in 2014; Black felt Suzanne Juul calot with feather studded leaves in 2015; Royal blue felt hat with side feather plume by Suzanne Juul in 2016

Repeat of the purple Jane Taylor pillbox in 2017; Black velvet bumper calot with side feathers by Suzanne Juul in 2018; Pink bumper calot by Suzanne Juul in 2019
UPDATE: Since this post was published, Crown Princess Mary has worn these additional hats to this event:

Repeat of the Suzanne Juul black velvet bumper in 2020
It’s a fairly dark hued group, save for a pair of autumnal tan designs and the pink bumper from last year. The royal blue plumed hat in 2016 is one of my favourites thanks to it’s dramatic shape and stunning hue, and the purple pillbox is lovely as well. Which pieces stand out most to you?
